Udomsubpuyakul U The authors investigated the one-month prevalence and associations of insomnia in an
elderly Thai population. A random sample of 40,111 individuals was selected from those of persons
over 60 years of age by multiple stage sampling. The subjects were interviewed using a sleep questionnaire.
Prevalence of insomnia of the population was 46.3 per cent. Depression and poor perceived
health were factors strongly associated with insomnia. On the basis of these findings, the authors consider
the prevalence of insomnia among the Thai elderly to be rather high. The implications of this
study are of great importance for the design and development of preventive strategies and community-
based interventions.
